What HiFi and Atmos

@kota1 Instead of height speakers: with the importance of the center speaker in 5.1, I need to upgrade mine (had limited choice, needed an ultra low profile).

What would be a good match for the Nautilus 804?

And no, I can't afford a Nautilus HTM1 or HTM2. More like a used CC6 (how bad is that one). 

This blueray has an atmos and a dts mix and a 3D and a HD disc. It is the best concert bluray and GREAT technically and artisitically:

For a CC how about a HTM-4

or HTM 2 $500:

yes, for headphone I listen to Apple Music Atmos music is awesome, but never try on AV RECEIVER multi channel system. 

The Sony 360 Reality Audio is even better on headphone.
